Study Notes
Broadband Internet Service Technologies
- Cable Internet Service: High-speed connection through cable television network via a cable modem. Speed decreases if many users are online simultaneously due to shared connection.
- Digital Subscriber Line (DSL): High-speed internet through standard telephone network via a DSL modem.
- Mobile Broadband/Cellular Radio Network: High-speed internet over cellular radio network using compatible technologies (3G, 4G, 5G). Provided by cellular network companies. Works with devices with built-in wireless modems.
- Fixed Wireless: High-speed internet using a dish-shaped antenna on a building. Communicates with a tower location using radio signals. Example: internet connections at hospitals, shopping complexes, and hotels.
- Fiber to the Premises (FTTP): High-speed internet using fiber optic cable via a modem. Fast but expensive and only available in limited areas.
- Satellite Internet Service: Provides high-speed internet access using a satellite dish. Useful in rural areas where other high-speed options are not available. Generally slower and more expensive than cable or DSL.
- Wireless Fidelity (Wi-Fi): High-speed internet connection using broadcast radio signals via a wireless router. Connects directly to an internet modem and acts as a hub to broadcast the signal to devices. Provided by organizations (e.g., shopping malls, restaurants) and offered as hotspots.
Broadband Advantages and Disadvantages
-
Advantages:
- Quick downloading and uploading of large files, streaming videos.
- Convenience: Always-on connection.
- Enhanced security options with real-time updates.
- Unlimited access without connection duration charges.
-
Disadvantages:
- High cost: Initial setup and monthly fees.
- Technical issues: Installation complexity, maintenance and downtime.
- Security risks: Cyber threats and data breaches due to always-on nature.
2.0 INTERNET TECHNOLOGY
2.6 The Internet Address
- IP address: A sequence of numbers that uniquely identifies the location of each computer or device connected to the internet.
- Purpose of IP address: Used to uniquely identify device locations to send data and information.
- Why we need IP addresses: To uniquely identify devices and enable communication and data exchange.
-
IP addressing schemes:
- IPv4: Made up of four groups of decimal numbers, formatted as four 8-bit fields separated by a period (.). Range for each group is from 0 to 255.
- IPv6: Replaces IPv4 due to increase in internet devices and lack of sufficient IPv4 addresses.
Relationship between IP address and domain name:
- Domain name: An easy-to-remember label for a website or server.
- IP address: Numerical address required for communication on the Internet.
- DNS (Domain Name System) translates domain names into associated IP addresses, enabling users to access websites using their names instead of numerical IP addresses.
